Patent document 1：Japanese Laid-Open 2000-120141 publications
Patent document 2：Japanese Laid-Open 2004-275985 publications
Patent document 3：Japan's examined patent publication 58-49300 publications
The content of the invention
First, the water discharge device that aproll nozzle was driven and changed the water direction for being spued as vibrating is deposited
In following problem, due to needing to drive nozzle, therefore the structure of nozzle periphery to complicate, it is difficult to which multiple nozzles are compactly received
In water discharge device.In addition, in the water discharge device of the type, there are the following problems, because nozzle carries out physical actions, therefore
Moving part is easily worn and torn, and in order to avoid abrasion, the material selection for constituting the component of movable part is restricted.It is additionally, since needs
Baroque moving part is formed with lost material is difficult to, therefore there is a problem of high cost.
On the other hand, because the injection apparatus of the type described in patent document 1 to 3 is showed using the vibration of flow element
As, it is not necessary to movable link is set and can just change the injection direction of fluid, therefore exist can be compact by simple structure
Constitute the advantage of nozzle segment.
But, present inventors found that following problem, is applied to by the flow element described in patent document 1 and 2
During the water discharge device of shower nozzle etc., the spray sense of the water for being injected is not outstanding.Here, inventor wants the outstanding of realization
Spray sense refer to the big water exhaustive of drop by spue to wider range state.That is, in the drop of the water spued from shower nozzle
Excessively hour, water is in vaporific, even if being sprayed by the water of isodose, cannot also obtain the sense of reality for being sprayed.In addition, if quilt
The water of discharge becomes uneven in the range of guttation, then cannot equably rinse user has the part expected and sprayed, and uses
Sense becomes poor.
Here, because the flow element described in patent document 1 and 2 make use of the fluid being ejected to be wanted because of wall attachment effect
Along the phenomenon that wall flows, therefore produced on to the fluid sprayed in the range of discharge uneven.That is, in the warm water shown in Fig. 9
In seat device, although the washing water being injected transition between state a, b, c, but actually jet flow is drawn towards the shape of wall
It is more long during state a and state c, and it is then extremely short during being in the state between these (near state b).Therefore, by specially
When flow element described in sharp document 1 and 2 is applied to the water discharge device of shower nozzle etc., the peripheral part in guttation scope is told
Less " hollow " state of guttation amount near water is more and central, spray sense becomes poor.
On the other hand, it is vortexed because the flow element described in patent document 3 applies toll bar, therefore is nearly free from spray
Stream is drawn towards wall while the phenomenon for flowing.Therefore, formed because guttation direction is changed as vibrating
Guttation in the range of, substantially uniform guttation amount can be obtained.But, present inventors found that following problem, will
When flow element as shown in Figure 10 is applied to the water discharge device of shower nozzle etc., the scope of reciprocating vibration of the water being injected strongly according to
Water-carrying capacity that Lai Yu is ejected and change.That is, in the flow element shown in Figure 10, if enlargement discharge and accelerated from going out
The flow velocity of the water of mouthfuls 112 injections, then water conflicted in wall 110a (or 110b) and significantly conversion direction with larger speed.
Therefore, in the state of flow is larger, wider range is expanded to relative to the water from the injection of outlet 112, if flow diminishes
Guttation scope diminishes.So, if guttation scope significantly changes with the change of flow, as awkward
Water discharge device.
So as to the technical problems to be solved by the invention are to provide a kind of water discharge device, can be compact by simple structure
Constitute, can obtain guttation easy to use.
In order to solve the above problems, the present invention is a kind of water discharge device, and water is made while carrying out of reciprocating vibration one from guttation mouthful
While being spued, have：Water discharge device body；And vibration generating element, the water discharge device body is arranged at, make the water being supplied to
Carry out of reciprocating vibration while being spued, it is characterized by, vibration generating element has：Water-feeding path, from water discharge device body
The water of supply is flowed into；Water conflict portion, to block a part for passage section for the water-feeding path in the way of configure in water-feeding path
End of downstream side, the conflict of the water because being guided by water-feeding path and be alternately produced rightabout vortex in side downstream；
Vortex row path, is arranged on the downstream of water-feeding path, the vortex formed by water conflict portion is grown up while entering to it
Row guiding；And rectifying path, the path in the downstream of the vortex row path is disposed on, to comprising being guided by vortex row path
Vortex be listed in water carry out rectification while being spued, a pair of relative walls of vortex row path entirety across
Changed with taper on degree, so that passage section product reduces towards downstream.
According to such present invention for constituting, due to that can be carried out by the water for vibrating generating element to make and being spued from water discharge device
It is of reciprocating vibration, therefore, it is possible to by compact and simple structure from 1 guttation mouthful to wider range discharge water.Further, since not
Needs activity guttation nozzle can just change guttation direction, therefore the problem of abrasion etc. occurs in the absence of movable part, can constitute
Low cost and durability water discharge device high.Further, since vibration generating element in vortex row path relative wall with
Taper changes, and so that passage section product reduces, therefore guttation scope will not depend upon the guttation flow of water and larger
Change, water discharge device easy to use can be constituted.That is, due in vortex row path flow water along this with bore
The wall flowing that shape changes, the flow direction of water is defined as approximately along the direction to the wall changed with taper, therefore
Guttation scope is difficult to result from the change of flow and changes, and guttation scope can be made substantially certain.
But, although can be flowed along the wall changed with taper by making water, so as to improve for guttation stream
The dependence of the guttation scope of amount, but produce new technical problem because of the structure.That is, the guttation for so obtaining is in guttation
Less " hollow " state of guttation amount near the water of the peripheral part of scope is more and central, tells as spray sense is not good
Water.Why so, it is contemplated that following reason, because water flows along the wall changed with taper, therefore produces attached wall
Effect, guttation concentrates on the periphery of guttation scope.Then, inventor of the invention makes to solve the new technical problem
Make the structure that the relative wall of vortex row path is changed in overall span with taper.So, invention of the invention
Person is led to by the structure for making the relative wall of vortex row path be changed with taper in overall span so as to be arranged in vortex
The water flowed in road will not be by larger pressure compaction in wall, and the wall attachment effect when being flowed out from rectifying path is inhibited,
Droplet distribution can equably be made in guttation scope.
Be preferably as follows in the present invention, the configuration of the downstream in water conflict portion compared with the upstream end of vortex row path closer to
The position in downstream.
According to such present invention for constituting, due to water conflict portion downstream configuration compared with the upstream end of vortex row path more
Near the position in downstream, thus the vortex row path changed with taper from compared with the downstream in water conflict portion closer to
The position of upstream side initially forms, and can effectively guide the vortex formed by water conflict portion.In addition, in vortex row path
The water of flowing will not can be reduced to being told by larger pressure compaction in the wall changed with taper of vortex row path
The wall attachment effect that the water for going out is acted.
Be preferably as follows in the present invention, the configuration of the upstream end in water conflict portion compared with the upstream end of vortex row path closer to
The position of upstream side.
According to such present invention for constituting, due to water conflict portion upstream end configuration compared with the upstream end of vortex row path more
It is located near the upstream end of the position of upstream side, therefore water conflict portion and is more leaned on compared with the vortex row path changed with taper
The position of nearly upstream side, vortex row can be efficiently formed by water conflict portion.
It is preferably as follows in the present invention, a pair of the walls changed with taper of vortex row path are relative to vortex row path
Central axis incline 3 ° to 25 °.
According to such present invention for constituting, can balancedly suppress the change of guttation scope that is produced by guttation flow and spue
When the wall attachment effect that produces.
According to the present invention, water discharge device easy to use compact can be constituted by simple structure.

And, inflow is vibrated the inflow entrance 4d of each vibration generating element 4 that generating element holding member 8 is kept.Produced from each vibration
The inflow entrance 4d of raw element 4 flows into the water of water-feeding path 10a, conflicts in the water conflict for the part for being configured to block its stream
Portion 14.Thus, it is alternatively formed the vortex row that rightabout toll bar is vortexed in the downstream in water conflict portion 14.Because of the water conflict portion
14 and formed toll bar be vortexed on one side guided by vortex row path 10b on one side grow up, and reach rectifying path 10c, vortex arrange
Path 10b tapered ground top attenuates.
Fig. 5 (a)~(c) represents the result parsed to the current in vortex row path 10b by fluid simulation.Such as
Shown in the fluid simulation, vortex is produced in the downstream in water conflict portion 14, flow velocity is uprised at the part.Flow velocity part high
(dark part in Fig. 5) is alternately present in the both sides in water conflict portion 14, and be vortexed wall court of the row along vortex row path 10b
Guttation mouthful 4a to advance.The water for flowing into the rectifying path 10c in vortex row path 10b downstreams obtains rectification herein.It is whole by this
The water that logical circulation road 10c spues from guttation mouthful 4a is based on the velocity flow profile at guttation mouthful 4a and is bent, along with flow velocity portion high
The upper and lower in Fig. 5 is divided to move up, and discharge direction changes.That is, the flow velocity of water part high is located at the guttation mouthful of Fig. 5
In the state of 4a upper ends, water is injected towards lower section, and flow velocity part high is located in the state of guttation mouthful 4a lower ends, and water is towards upper
Side is injected.So, it is vortexed by being alternately produced toll bar in the downstream in water conflict portion 14, so as to produce stream at guttation mouthful 4a
Speed distribution, jet flow is partial to.Further, since the position of before row and then velocity ratio part faster is back and forth transported because being vortexed
It is dynamic, thus the water being injected be also carried out it is of reciprocating vibration.
Further, since end difference 12 is provided between vortex row path 10b and rectifying path 10c, hence along vortex
The wall changed with taper of row path 10b and the current that flow are stripped and flow into rectifying path 10c herein.Due to water
Stream is stripped because of the end difference 12 from wall, therefore the wall attachment effect produced on the wall of rectifying path 10c is inhibited,
The water spued from guttation mouthful 4a is swimmingly moved back and forth.So as to end difference 12 peels off the wall along vortex row path 10b
The current of flowing, play a role as the stripping portion for suppressing wall attachment effect.
On the other hand, as comparative example as shown in fig. 6, in the vibration generating element of structure as shown in Figure 10, although
The vortex that toll bar is vortexed has been produced to arrange in the downstream in conflict portion, but the water being injected significantly occurs partially at guttation mouth
To the guttation scope of the water being injected excessively becomes wide.In addition, if reducing the water-carrying capacity for being spued and being simulated, this is then
Excessively generation is not partial to and guttation scope diminishes to have confirmed the water being injected.On the other hand, in the vibration of present embodiment
In generating element 4, having confirmed can just obtain appropriately sized guttation scope by the flow than wider range.
Next, as shown in Fig. 7 (a), the stroboscopic of the current spued in the vibration generating element 4 represented from present embodiment
In photograph, because guttation direction is swimmingly moved back and forth, therefore regular sinuous current are can obtain.With this phase
Right, used as comparing shown in such as Fig. 7 (b), although the water that the vibration generating element of the structure shown in Figure 10 spues carried out back and forth
Vibration, but there occurs bow action.Why so, because the change in the discharge direction of water and having some setbacks, it is partial to angle
Time when maximum is more long, and the time that jet flow is moved between maximum angle of deflection degree is shorter.So, according in present embodiment
Vibration generating element 4, the drop that can obtain big grain equably spues to the outstanding injection guttation of the spray sense of wider range.
Next, reference picture 8 is illustrated to the shower nozzle involved by the 2nd implementation method of the invention.
The shower nozzle of present embodiment be the access structure of the vibration generating element being built with the 1st above-mentioned implementation method not
Together.So as to, present embodiment and the difference of the 1st implementation method are illustrated at this, omit to identical structure, make
With the explanation of, effect.
Fig. 8 (a) is the vertical view cutaway drawing of the vibration generating element in the 2nd implementation method of the invention, and (b) is that vibration is produced
The side view cutaway drawing of element.
As shown in Fig. 8 (a), vibrate generating element 20 the rectangular cross section for being internally formed insertion in the longitudinal direction it is logical
Road.The path from upstream side in order as water-feeding path 22a, vortex row path 22b, rectifying path 22c and formed.
Water-feeding path 22a is broken from the certain rectangle of the basal area of the inflow entrance 20d extensions of the vibration rear side of generating element 20
The linear path in face.
Vortex row path 22b is be set in the way of the downstream of water-feeding path 22a is to be connected to water-feeding path 22a rectangular
The path of shape section.That is, the downstream of water-feeding path 22a is of the same size shape with the upstream end of vortex row path 22b.
Relative a pair of walls (two sides) of vortex row path 22b are changed with taper, so as to towards downstream-side channel basal area
Reduce.That is, vortex row path 22b width in the way of attenuating towards downstream becomes narrow gradually.
The rectangular cross section that the mode that rectifying path 22c is attached to vortex row path 22b downstreams is set it is logical
Road, basal area is certain and linearly to be formed.So as to rectifying path 22c has the downstream identical with vortex row path 22b
Size shape, passage section product is also identical.
On the other hand, shown in such as Fig. 8 (b), water-feeding path 22a, vortex row path 22b and rectifying path 22c are in height side
Relative wall (top surface and bottom surface) is all disposed on the same plane upwards.That is, water-feeding path 22a, vortex row path 22b and
The height of rectifying path 22c is all identical and certain.
Next, in the end of downstream side of water-feeding path 22a, (water-feeding path 22a is attached with the connecting portion of vortex row path 22b
Water conflict portion 24 is formed with the way of closely) to block a part for passage section of water-feeding path 22a.The water conflict portion 24 be with
The part of the triangular prism shape that the mode of link water-feeding path 22a relative in the height direction wall (top surface and bottom surface) extends,
With island configuration in the center of the width of water-feeding path 22a.The rectangular equilateral triangle shape of section in water conflict portion 24, its
Hypotenuse be configured to it is orthogonal with the central axis of water-feeding path 22a, in addition, the right angle portions of section are configured to towards downstream
Side.By setting the water conflict portion 24, so as to produce toll bar to be vortexed in side downstream, the water spued from guttation mouthful 20a carries out past
Multiplex vibration.
Also, in present embodiment, the angle (Fig. 8 being made up of side wall and the central axis of vortex row path 22b
Angle [alpha] in (a)) it is for about 7 °.It is preferred that, the angle initialization that will be made up of side wall and central axis is into about 3 ° to about 25 °.It is logical
Such set angle is crossed, the change of the guttation scope with discharge flow change can be suppressed, while suppressing to produce wall attachment effect.
And, the passage section product of the part that the parts of rectifying path 22c downstreams is blocked by water conflict portion 24 is led to more than rectification
The passage section product of road 22c.
Although (the stripping of end difference 12 in being not provided with the 1st implementation method in the vibration generating element 20 of present embodiment
From portion), but even if in the present embodiment, carried out in the angular range of the water also Fitness degree spued from guttation mouthful 20a reciprocal
Vibration, at the same will not because spue water flow and discharge scope significantly changes.Why so, because due to whirlpool
Cone angle (angle [alpha]) in rotation row path 22b is smaller, therefore the water flowed in vortex row path 22b will not be forced by larger
Tightly in side wall.Thus, it is believed that fully it is stripped from the vortex row path continuous rectification stream 22c reclaimed waters of 22b, attached wall
Effect is suppressed.
Shower nozzle according to the embodiment of the present invention, due to that can make to be spued from shower nozzle 1 by vibrating generating element 4,20
Water carry out it is of reciprocating vibration, therefore, it is possible to by compact and simple structure from 1 guttation mouthful to wider range discharge water.Separately
Outward, because the relative wall of vortex row path 10b, 22b in vibration generating element 4 is changed with taper, so as to stream
Basal area reduces, therefore guttation scope will not depend upon the guttation flow of water and significantly change, and can constitute makes
With convenient shower nozzle 1.The relative wall for being additionally, since vortex row path 10b, 22b is become in overall span with taper
Change, thus the water flowed in vortex row path 10b, 22b will not by pressure compaction higher in wall, from rectifying path 10c,
Wall attachment effect when 22c flows out is inhibited, and drop can be made to be distributed evenly in guttation scope.
In addition, according to the shower nozzle of present embodiment, because vortex row path 10b, 22b is under the portion 14,24 that conflicts with water
Trip end compared to starting to be set closer to the position of upstream side, therefore vortex row path 10b, the 22b changed with taper from
Initially formed closer to the position of upstream side compared with the downstream in water conflict portion 14,24, can effectively guided because of water conflict
Portion 14,24 and formed vortex.In addition, the water flowed in vortex row path will not be logical in the row that are vortexed by larger pressure compaction
The wall changed with taper of road 10b, 22b, can reduce the wall attachment effect that the water to being spued is acted.
And, according to the shower nozzle of present embodiment, due to vortex row path 10b, 22b from the upper of portion 14,24 that conflict with water
Trip end closer to the position in downstream compared to starting to be set, therefore the upstream end in water conflict portion 14,24 is located at and is sent out with taper
Vortex row path 10b, the 22b for changing, being capable of efficient landform by water conflict portion 14,24 compared to the position closer to upstream side
Arranged into being vortexed.
More than, although the preferred embodiment of the present invention is illustrated, but above-mentioned implementation method can be added
Various changes.Especially, in the above-described embodiment, although apply the present invention to shower nozzle, but the present invention can also be answered
